Description

Laser cutting machine with high-efficient dust collector Technical Field The invention relates to the technical field of laser cutting equipment, in particular to a laser cutting machine with an efficient dust removing device. Background The laser cutting technology is widely applied to industrial production as a high-precision and high-efficiency metal plate processing method. However, during laser cutting, high energy density laser beams, when applied to the surface of a metal sheet, produce a large amount of high temperature fumes and splashed particles. The pollutants not only can diffuse in the working cavity of the equipment to seriously pollute the surface cleanliness of the cut plate and influence the quality of products, but also can be adsorbed on precision parts such as optical lenses, guide rails and the like of the laser cutting machine, so that the equipment precision is reduced and the service life is shortened. The existing laser cutting machine is usually provided with a dust removing device, but the problems of low dust removing efficiency, inconvenient dust removing and the like generally exist. For example, the traditional single-point smoke-absorbing cover is difficult to comprehensively capture smoke dust generated in the cutting process, particularly a large amount of particles falling off from a plate in the blanking process are easy to fly for the second time, the filter cylinder in the filtering unit is easy to block after working for a long time, and the filter cylinder needs to be frequently shut down for manual cleaning or replacement, so that the continuous production rhythm is interrupted, the maintenance cost and the working strength are increased, and the overall working efficiency of the laser cutting machine is seriously influenced. Therefore, there is a need to optimize and improve the existing dust removing system of the laser cutting machine, develop an integrated dust removing device which can efficiently collect smoke dust, automatically clean filter materials, reduce maintenance frequency, and effectively reduce interference of deslagging operation to the laser cutting process, so as to meet urgent demands of modern manufacturing industry on efficient and clean production.
